- Monsoon Awareness Week: Lightning Safety
- Date posted
- 9 months ago
- Description
- Monsoon Awareness Week: Lightning is the MOST UNDERRATED weather hazard! On average, only extreme heat and floods kill more people. Lightning makes every single thunderstorm a potential killer, whether the storm produces one single bolt or ten thousand bolts. Tornadoes, hail, and wind gusts get the most attention, but only lightning can strike well outside the storm itself. Lightning is often the first thunderstorm hazard to arrive and the last to leave.
Here are some things you can do to ensure your safety when thunderstorms are present: Watch for signs of an approaching thunderstorm. Postpone outdoor activities if thunderstorms are imminent. This is your best way to avoid being caught in a dangerous situation REMEMBER if you can hear thunder, you are close enough to a storm to be struck by lightning
Get inside a house, large shelter or an all-metal vehicle (not a convertible). If a safe shelter is not available, find a low spot away from trees, fences, and poles. ...

Monsoon Awareness Week: Are you planning a boating excursion this summer? Before you go out on the water, check the forecast and ensure your boat has the essential and required safety equipment and communications tools.
Grab that life jacket and "Wear It!" Nearly 85 percent of those who drown while boating were not wearing a life jacket. Wearing a life jacket is one of the most effective and simple life-saving strategies for safe recreational boating.
Weather can make your time on the water wonderful or deadly. It is vital to know how to respond to thunderstorms and/or rapid wind shifts and other dangerous weather. Thunderstorms can develop quickly and create dangerous wind and wave conditions. Remember, all thunderstorms produce lightning, and they can bring shifting and gusty winds and torrential downpours, which can turn a day's pleasure into a nightmare of distress.
Boaters should use extra caution wh...

- Monsoon Awareness Week 2023: Debris Flow
- Date posted

Monsoon Awareness Week: Debris flows are dangerous land and water flows caused by heavy rainfall in areas of steep terrain and loose-bare soil. Flash flooding and debris flows are common in or near wildfire burn scars, so unfortunately many areas within the American Southwest are susceptible to their impacts.
Burned soil can be as water repellant as pavement. When vegetation is burned at high intensity, water-repelling compounds are vaporized and then condense on the soil layers below which prevents soil from absorbing water. This leads to excessive runoff whenever rain falls, resulting in flash flooding and the development of debris flows. Accumulations of ash, soot and burned logs are just a few of the things that wildfires will leave behind, and this debris can quickly move downstream and create a pathway of damage when flooding occurs. #Monsoon2k23

Monsoon Awareness Week: Flash Floods are a real threat during the monsoon. Flash Floods occur when rain falls too fast or heavily for the ground to absorb the water. This leads to runoff which can turn excessive, quickly filling normally dry washes, arroyos, ditches, low water crossings and creek beds. Flash floods occur quickly, and the torrents of water that they can produce will move at very fast speeds. These torrents can roll rocks, tear out trees, sweep away cars and trucks, and destroy buildings and bridges. Flash flood-producing rains can also trigger catastrophic mudslides or debris flows.
Do not attempt to drive over a flooded road. The depth of the water is not always obvious. Most flood deaths occur in vehicles, so if you encounter water flowing over a road it’s important to remember: “Turn Around, Don’t Drown!” #Monsoon2k23

Monsoon Awareness Week: We love outdoor activities, especially hiking and camping! However, it’s important to remain weather-aware before you head outside. Check the forecast beforehand, and know what to expect, as the monsoon can abruptly bring thunderstorms and associated weather hazards. Know before you go!
Once you do head outdoors, keep your guard up! Stay alert and keep an eye on the skies. Look for bubbling cumulus clouds, the building blocks of thunderstorms, and have a plan to take shelter in a sturdy structure should storms become imminent.
If camping, plan where you will pitch your tent. Stay out of washes, arroyos, dry creeks or river beds, as flash flooding can abruptly impact these areas, even if it’s not raining directly on you. Thunderstorms may be occurring miles upstream, leading to runoff that could send torrents of water downstream into these normally dry drainage areas. #Monsoon2k23

Monsoon Awareness Week: Strong thunderstorm winds, or even downburst winds, can create areas of blowing dust during the Monsoon. Blowing dust can quickly reduce visibility, posing hazards to travelers and motorists.
If you are driving and encounter extremely low visibility in a dust storm:
Pull OFF the side of the road
Lights OFF to ensure others don’t try to follow your taillights
Foot OFF brake
Stay in the vehicle with your seat belts buckled and wait for the dust storm to pass. #PullAsideStayAlive #Monsoon2k23

Monsoon Awareness Week: Downburst winds are commonly associated with thunderstorms during the Monsoon and they can be extremely hazardous. Downburst winds are one of the thunderstorm-related weather hazards most likely to produce property damage.
A downburst is a non-rotating wind that is created by a column of sinking air in a thunderstorm that, after hitting ground level, spreads out in all directions and is capable of producing damaging straight-line winds of over 100 mph. These winds can often produce damage similar to, but distinguishable from, that caused by tornadoes. The physical properties of a downburst are completely different from those of a tornado.
Rain falling from a thunderstorm will create a column of cool air that will sink along with the rain. This is known as a downdraft. As rain descends some of it may evaporate, leading to additional cooling of the downdraft. This evaporative cooling can cause ...

Monsoon Awareness Week has begun! One weather hazard that often accompanies the early part of the monsoon is heat. Heat is often at its worst across the American Southwest before monsoon thunderstorms become widespread, but it can also become problematic during drier stretches within the heart of the season.
"But it's a dry heat..." Many residents and visitors to the desert Southwest think since relative humidity is low, they need not worry about heat stress. While high relative humidity can certainly increase the adverse effects of heat on the human body, the hottest of days during the monsoon can still result in numerous health issues such as heat exhaustion and heat stroke. #Monsoon2k23

It’s Monsoon Awareness Week! Each day this week we will be discussing various topics related to the North American Monsoon, a season when some locations within the American Southwest can receive a majority of their annual rainfall. However, it’s not just about the rainfall! Unfortunately, there are various weather hazards that can accompany the beneficial rainfall.
Monsoon Season is defined as the seasonal reversal of winds from June 15th through September 30th. That doesn’t necessarily mean that thunderstorms will only develop during these dates, but rather this is a time of year to stay alert and aware of monsoon hazards, much like hurricanes have a defined season to stay prepared and ready for potential storms. Stay tuned this week as we take a deep dive into the potential hazards during the monsoon, so that we can keep you informed on how to stay safe! #Monsoon2k23
